Question

The sum of first three common multiples of 3, 4 and 9 is

Answer 1

Hi,

First we have to find out common multiples

of 3 , 4 and 9,

For that find L.C.M of 3 ,4 and 9

3 | 3 , 4 , 9
__________
1 , 4 , 3

L. C.M ( 3 , 4 ,9 ) = 3 × 4 × 3 = 36

Now multiples of 36 = { 36 , 72 , 108 , 144, ....}

Aum of first three common multiples

of 3 , 4 , and 9 = 36 + 72 + 144 = 252

I hope this helps you.
